Hard Disk Drive
If you have problems with the hard disk drive, run the Microsoft Windows disk checking utility. This utility analyzes the
directories, files and File Allocation Tables (FAT).
Right-click the Computer or Local Disk icon, then click Properties > Tools > Error checking then click the Check now
button. Contact your representative if the scandisk utility does not report any errors and the hard disk still has problems.
For information on running the disk checking utility, refer to Help and Support on the Windows Start menu.

Microsoft Windows controls memory management. If you experience a problem with memory management, please refer to
Help and Support on the Windows Start menu or a commercially available Windows guide. If a particular program causes the
memory error, refer to the documentation for that program.
